What is wrong with my code???

Let's get in some slice practice! Create a new variable named slice1 that has the second, third, and fourth items from favorite_things.

slices.py 
favorite_things = ['raindrops on roses', 'whiskers on kittens', 'bright copper kettles',
                   'warm woolen mittens', 'bright paper packages tied up with string',
                   'cream colored ponies', 'crisp apple strudels']
slice1 = favorite_things
slice1 = [1:3]

I believe it needs to be slice1 = favorite_things[1:4]

The second element refers to index 1, third element to index 2, and fourth element to index 3. The slice will include index 1 all the way up to but not including index 4.

I see two issues:

  • the slice numbers in brackets must come directly after the name of the list
  • as Kyle pointed out, the "stop" number is the index to stop before

Sorry to necro this, but just now going through the program. Maybe this would be helpful to others in the future.

I did the same thing and over-complicated it. I wrote mine as:

slice1 = favorite_things[:] slice1[1:4]

When it really just needed to be "slice1 = favorite_things[1:4]" for the challenge. Although, mine wasn't wrong, it was just less concise with an extra step in there.
